Quick answer
With our UK defaults (£290,000 home, £1,350 rent, 4.3% mortgage, 10% deposit), buying pulls ahead of renting within about two years and finishes roughly £100,000 better off after ten. UK maths favours buying because deposits are small, selling costs are low and first-time buyers pay little Stamp Duty. Expensive leaseholds, London prices and short stays are where renting wins.
Rent vs buy calculator UK: how do you use it?
Enter the purchase price, a comparable monthly rent, your mortgage rate and deposit, then add Stamp Duty and fees to buying costs. With our UK defaults, buying beats renting within about two years and leaves you roughly £100,000 better off after a decade, because UK deposits, selling fees and first-time buyer Stamp Duty are all relatively low.
The calculator simulates every month of your chosen horizon. The buyer pays the deposit and buying costs, then the mortgage, maintenance and buildings insurance; the renter pays rent and contents insurance and invests what the buyer spent upfront. Whoever has the lower monthly outgoing invests the difference. When the horizon ends, the buyer sells (paying estate agent and conveyancing fees) and we compare net worth. Our methodology page explains each step.
Why our UK defaults look the way they do
| Input | Default | Reasoning |
|---|---|---|
| Purchase price | £290,000 | Close to the UK average house price |
| Monthly rent | £1,350 | A typical UK private rent for a similar home |
| Mortgage rate | 4.3% | A mid-range fixed rate for a 90% loan-to-value deal |
| Term / deposit | 25 years / 10% | The classic first-time buyer setup |
| Council tax | 0% | Paid by tenants and owners alike, so it cancels out |
| Buying costs | 2.5% | Solicitor, searches, survey, lender fees; no SDLT for a first-time buyer at this price |
| Selling costs | 2% | Estate agent (often 1–1.5% plus VAT) and conveyancing |
| Maintenance / insurance | 1% / 0.15% | Repairs budget and buildings insurance |
| Price / rent growth | 3% / 4% | Rents have outpaced prices in recent years |
| Investment return | 6% | A global tracker in a Stocks and Shares ISA, so largely tax-free |
Worked example: renting vs buying a £290,000 home
Deposit and costs: £29,000 deposit plus £7,250 in fees = £36,250 upfront. The renter invests that instead.
Monthly mortgage payment: £261,000 borrowed at 4.3% over 25 years is £1,421 a month on a repayment mortgage (calculated with the standard amortisation formula). In year one, about £11,100 of what you pay is interest and about £5,900 reduces the loan.
Owner running costs: maintenance (£242) and buildings insurance (£36) add about £278 a month, for a total of roughly £1,700 against £1,360 for the renter (rent plus contents cover). The renter invests the £340 gap each month.
After 10 years: buying finishes roughly £100,000 ahead. The break-even year is about year two and the break-even rent is around £800 a month — you would need to rent a comparable home for less than that for renting to win. The 5% rule points the same way: £290,000 × 5% ÷ 12 = £1,208, below the £1,350 rent.
Why the UK result leans to buying: the renter only has £36,250 to invest, while the buyer controls a £290,000 asset with that same money. Even at 3% growth, that leverage plus 2% selling costs beats a 6% return. Raising the rate to 4.9% trims the buyer’s lead by around £18,000 but doesn’t flip the verdict.
What are the costs of buying and selling in the UK?
| Cost | Typical amount | Notes |
|---|---|---|
| Stamp Duty Land Tax (England & NI) | £0 for first-time buyers up to £300,000 | 5% on £300,001–£500,000; no relief above £500,000 |
| SDLT for home movers | £4,500 on a £290,000 home | 0% to £125,000, 2% to £250,000, 5% above |
| Conveyancing and searches | ~£1,500–£2,500 | Leasehold transactions cost more |
| Survey | ~£400–£1,500 | Level 2 or Level 3 survey |
| Mortgage arrangement fee | £0–£1,500 | Often traded off against a lower rate |
| Estate agent (selling) | ~1–1.5% + VAT | Online agents charge flat fees |
| Leasehold pack / management fees | Several hundred pounds | Paid when selling a leasehold flat |
Stamp Duty in 2026: what first-time buyers pay
According to HM Revenue & Customs’ current rates, the standard bands since 1 April 2025 are 0% up to £125,000, 2% to £250,000, 5% to £925,000, 10% to £1.5 million and 12% above. First-time buyers pay nothing on the first £300,000 and 5% on the slice up to £500,000. A first-time buyer at £450,000 pays £7,500; at £550,000 the relief vanishes and the bill jumps to £17,500. Buyers who already own another home usually pay an extra 5% on every band. The October 2026 Budget left SDLT unchanged.
Scotland charges Land and Buildings Transaction Tax and Wales charges Land Transaction Tax, each with different bands and, in Wales, no first-time buyer relief. Check Revenue Scotland or the Welsh Revenue Authority and add the result to buying costs.
How do UK mortgages and remortgaging affect the result?
Most UK borrowers fix for two or five years, then remortgage or roll onto the lender’s standard variable rate, which is usually much higher. That means your rate is guaranteed only for the fixed period, not the 25-year term. On the default loan, after two years you’d owe about £248,800. Remortgaging at 5.5% for the remaining 23 years would push the payment to about £1,590; at 3.5% it would drop to about £1,310.
Because the calculator uses a single rate, enter your best estimate of the average rate across the horizon, then stress-test it. Lenders already do something similar: affordability checks typically test whether you could cope with rates higher than your initial deal, and lend around 4.5 times income for most borrowers.
Other tools that change the numbers:
- Lifetime ISA (LISA): savers aged 18–39 can pay in up to £4,000 a year and get a 25% government bonus, usable on a first home costing up to £450,000. The government has announced a new First Time Buyer ISA to replace the LISA for new savers from April 2029, and in the October 2026 Budget said the withdrawal penalty for buying a home above £450,000 will fall from 25% to 20%. Include any bonus in your deposit.
- Shared ownership: if a full purchase is out of reach, our shared ownership calculator models buying a 10–75% share and paying rent on the rest.
Leasehold, service charges and council tax
Most UK flats are leasehold. You own the right to live there for the length of the lease, and the freeholder or managing agent charges an annual service charge for building insurance, cleaning, lifts and repairs, sometimes with ground rent on top. Service charges of £1,500–£4,000 a year are common in purpose-built blocks, and can spike for major works. Enter them as a monthly fee — they are paid only by owners, so they matter to the comparison. Short leases (under about 80 years) cost more to extend and can make a flat hard to mortgage.
Council tax is excluded by default because tenants pay it too. The exception is when the home you’d buy is in a different band from the one you’d rent.
How do London, Manchester, Birmingham, Edinburgh and Bristol compare?
- London: prices of £550,000 and up mean first-time buyers often lose Stamp Duty relief, gross rental yields are often under 5%, and many homes are leasehold flats with service charges. A 10% deposit on £550,000 means a £2,450 monthly payment over 30 years. Renting frequently wins over short horizons; see our UK rent vs buy guide.
- Manchester: lower prices and strong rent growth make buying favourable for most stays over a few years. Watch service charges on city-centre new-build flats.
- Birmingham: prices below the national average with solid rents; buying usually wins quickly on our defaults.
- Edinburgh: use LBTT instead of SDLT, and note that Scottish rent rules differ from England’s.
- Bristol: high prices relative to local incomes but also high rents; the result is often close and depends heavily on how long you stay.
When does renting win vs buying in the UK?
Renting tends to win when:
- You may move within two to three years, before buying and selling fees are recovered.
- You are buying above £500,000 as a first-time buyer and lose Stamp Duty relief.
- The flat is leasehold with high or rising service charges, or a short lease.
- You’d remortgage at a rate well above today’s fixes and the rent on a similar home is cheap.
Buying tends to win when:
- You plan to stay five years or more.
- Your deposit is small relative to the price, so leverage works hard for you.
- Rents in your area are rising faster than prices, as they have in much of the UK.
- You can buy freehold or a leasehold with modest, well-managed service charges.

UK renting vs buying checklist
- Work out Stamp Duty (or LBTT/LTT) for your exact price and status, and add it to buying costs.
- Get a solicitor’s quote; leasehold conveyancing costs more.
- Enter service charge and ground rent as a monthly fee.
- Use a rate that reflects your fix plus what you’d likely remortgage at.
- Add any LISA bonus to your deposit.
- Compare the break-even rent with real listings in the same postcode.
- Set the horizon to how long you expect to stay, not the mortgage term.

Frequently asked questions
Is it better to rent or buy in the UK in 2026?
For most first-time buyers outside London who plan to stay at least three to five years, buying comes out ahead on our defaults because a 10% deposit, low selling fees and Stamp Duty relief keep upfront costs small. Renting is often better in central London, for short stays, or for leasehold flats with high service charges.
How much Stamp Duty will I pay as a first-time buyer?
In England and Northern Ireland, first-time buyers pay no Stamp Duty Land Tax on the first £300,000 and 5% on the portion between £300,001 and £500,000. If the price is above £500,000, the relief is lost entirely and standard rates apply. Scotland and Wales have their own taxes with different thresholds.
Why does the calculator exclude council tax?
Council tax is paid by whoever lives in the property, so renters and owners pay the same bill for the same home. Because it doesn't change the comparison, our UK default sets property tax to 0%. If you are comparing homes in different council tax bands, add the difference as a monthly fee.
How do I model a two-year or five-year fix?
The calculator uses one rate for the whole term, so enter the rate you expect to average over your horizon. If you are fixing for two years at 4% but expect to remortgage at around 5%, try 4.5%, then test higher and lower rates to see how sensitive your result is.
Should I include service charges for a leasehold flat?
Yes. Enter the annual service charge plus any ground rent as a monthly fee. A £2,400-a-year service charge is £200 a month. This often matters more than the mortgage rate for flats, because service charges can rise sharply when major works are due.
Can I use a Lifetime ISA with this calculator?
Yes, indirectly. The 25% government bonus on up to £4,000 a year effectively increases your deposit. Enter your total deposit including the bonus. Remember the bonus applies only to homes up to £450,000 and the account must be open at least 12 months before you use it to buy.
